Galiffi relocated to Brazil, and Nebbia left the group in 1969; by 1970, Los Gatos had dissolved. Nebbia began a solo career with RCA Records, and his first album, Litto Nebbia, benefited from having a number of its tracks included in local filmmaker Julio Porter's El extraño de pelo largo (The Long Haired Stranger). His work drew from the folklorical Chacarera genre in 1971 and 1972, and in 1973, he founded the Litto Nebbia Trio, whose repertoire centered on jazz. Nebbia produced folk rock duo Pastoral's En el hospicio (In the Hospice) in 1975, enjoying success in his first foray into record production. The advent of a new dictatorship in 1976, and his subsequent intimidation and detainment, forced Nebbia to seek exile in Mexico, however. He remained creatively productive in exile, and released some of his most successful albums during this era, including Canciones para cada uno (Songs for Each of You) in 1978, and Sólo se trata de vivir (It's Only About Living), in 1981. Expecting a daughter, Miranda, and heartened by an improving civil liberties climate, Nebbia returned to Argentina in 1982. His return was followed by the Rosariazo, a May 1983 concert in which he was joined by chanteuse Silvina Garré, Juan Carlos Baglietto, and Fito Páez, among others; his 1986 release, Demasiadas maneras de no saber nada (Too Many Ways to Know Nothing), was his fiftieth. Martha Nebbia, his mother, had recently converted a former Villa Urquiza shoe store into her new residence, and invited her son to install a recording booth there. Reunited with Salvador Barresi, the recording engineer from his days with Los Gatos, they improved and equipped the ad hoc space, which was opened as a recording studio in 1988, and which Barresi named El Nuevo Mundo ("The New World"). El Nuevo Mundo Studios led to Nebbia's 1989 establishment of Melopea Records, which he named after both the Ancient Greek music theory, and his own, 1974 album of that name. Melopea Records became known for discovering and promoting new talents, as well as producing unreleased tango compositions from decades earlier. Some of these latter included works by consular figures in the genre, such as Juan Carlos Cobián, Enrique Cadícamo, and Roberto Goyeneche. Nebbia was named Illustrious Citizen of Buenos Aires in 2002. Los Gatos, save for drummer Oscar Moro (who had died a year earlier), were reunited for a revival in 2007. Nebbia
